maybe we should first focus on I2a-Din- south as it is younger and less wide spread.... so it should give us better clue of more recent history of I2a-Din that is present on Balkan

what we see besides Balkan, is settlement around Krakov in south Poland, which is most likely about white Croatia, we see line from Leipzig via Bohemia towards Vienna, which is likely about white Serbia, we see area in north Poland which corresponds to location of Germanic Scirii in times 1AD-200AD
http://www.euratlas.net/history/europe/1/entity_3837.htmlhttp://www.euratlas.net/history/euro...ntity_3837.jpgnote that Germanic Scirii are often coupled with Germanic Hirri, in same way as Serbs and Croats are coupled...we also see a line that goes from Hamburg, via Hanover to Frankfurt and Zurich, which is hard to explain....perhaps Helvetii...
it is possible that I2a-Din south came to existence among Germanic people around Hamburg and from there it took two routes: one going southwards towards Zurich and the other went towards east and settled in north Poland e.g. under name Scirii(which is in my opinion of same origin as tribal names Serian, Zeruiani, Sherdana...)
Scirii moved a lot accross east Europe and it is plausible that eventually they became Slavic speakers....
I2a-Din North on other hand seems to have been already present in Balkans in distant past, so I think this is about Scordisci and much earlier about Sherdana sea peoples...
so I expect that I2a-Din North in Kurds is North variant...
I also think that I2a-Din North might have been Celtic people in historic times.... here Scordisci and Helvetii come to my mind... Scordisci who lived along Danube are likely Serians of Seneca who cross frozen Danube on bare foot.. while Scirii might be Serians of Seneca who rule over scattered Scythians....
Scordisci fits with Russian primary chronicle speaking of Serbs among Danubian Slavs who were pushed out to north by Vlakhs (Romans)... Russian primary chronicle records collective memory of past, but those memories would probably skip language transitions, leaving possibility that those so called Danubian Slavs were not yet Slavic speaking at the time they lived around Danube... note that Scordisci lived mixed with Illyrians and thus must have incorporated significant E-V13 and also some of J haplogroups... that would explain why spread of E-V13 is relatively homogenous in Serb settled areas and much higher than in Croats ...
Scordisci just lived and moved along Danube basin... so when pushed from Serbia they would naturally end up in Bohemia which is where they probably also originally came from... end Bohemia is land Boiki (that neighbours Frankia on west and white Cratia on east) from where white (west) Serbs came to Balkan to make Serbs of today....

note that historic record states Serbs come to Balkan from land of Boiki where they have also originally dwellt... such statement implies there was no continuity, it implies they originally dwellt in Boiki than spread elsewhere, returned to it, and only than came to Balkan...
note that according to some sources molecular diversity of I2a-Din seems to be much higher in Serb settled areas, Bohemia, and Ukraine than e.g. in Croatia indicating much earlier presence in these regions... this if correct, excludes I2a-Din being Illyrian genetics and points out that expansion of I2a-Din to Croatia happened only with Slavs, while I2a-Din in Serbia was also present before Slavs... thus, Scordisci...
